Another bunk bed design, this one based on interim Autobot leader Ultra Magnus. His car carrier/transport alt-mode is ideal for a bunk bed configuration, with the truck cab being used for storage.
If you want to take this idea even further, you could park a few car beds on it (both given an Autobot makeover of course), but that would require an even bigger Ultra Magnus.
Side note: here is a cool Optimus Prime bunk bed that was made for a couple of lucky rugrats.
